Tables & Results: Microbiological Testing Program Pasteurized Egg Products

The tables have been divided from 1995 to 1999, from 2000 to 2007, and from 2008 to 2017 because beginning in January 2008, FSIS began reporting microbiological results by collection date as opposed to analysis end date.

Table 1a shows the results for the seven egg product categories by year from 1995 through 1999; Table 1b shows the results by year from 2000 through 2007; and Table 1c shows the results by year from 2008 through 2017. Tables 1d and 1e show combined data from 1995-2007 and 2008-2017, respectively.

Figure 1a and Figure 1b have been divided into year ranges to reflect changes in reporting. The results from 2008 and after cannot be compared with previous years.

Since the beginning of sample collection, FSIS has identified 111 positive pasteurized egg products samples. FSIS obtained serotype information on 96 of these positive isolates. The serotype data from 1995 through 1999 are presented in Table 2a, from 2000 through 2007 in Table 2b, and from 2008 through 2017 in Table 2c; the total sum from all the years from 1995 through 2017 are presented in Table 2d.

The four most common Salmonella serotypes identified were Heidelberg, Enteritidis, Typhimurium, and Braenderup.

Analysis of all egg products for Listeria monocytogenes started on September 21, 2016.

Table 3a and Table 3b show Listeria monocytogenes-positive sampling results for the seven egg product categories by year and combined data from 2016-2017, respectively.

Figure 3 graphically shows the results for Listeria monocytogenes-positive samples by year from 2016-2017.

Summary from the data:  The incidence of Salmonella and Listeria continues to be low. In 2017, FSIS reported a percent positive rate for Salmonella and Listeria of 0.00 and 0.06%, respectively.

FSIS provides links to the Centers for Disease Control and Prevention (CDC) data on the serotypes isolated from human cases of salmonellosis. The reader can easily access the data on both the serotypes found in pasteurized egg products and those causing human illness on the following websites:

Figure 1a shows the Salmonella percent positives in pasteurized egg products from 1995 to 2014 (0.35%), which is the time period FSIS has managed the program.

The Salmonella percent positives (0.19%) observed from 2008 through 2014 are illustrated in Figure 1b. Figure 1b also demonstrates a downward trend in percent positives from 2008 to 2014.
